THE ANNALS AND MAGAZINE OF NATURAL HISTORY SUPPLEMENT TO VOL. X. JANUARY 1843. XLV. — Notices of Fungi in the Herbarium of the British Museum. By the Rev. M. J. Berkeley, M.A., F.L.S. [With Four Plates.] The greater part of the Fungi described in the present me-moir were collected by Konig in Ceylon, a country which has hitherto made very slight contributions to mycology. They consist principally of Polypori, which, with the exception of one or two cosmopolites, are new. Konig had evidently in most cases well distinguished the species, and probably in-tended to publish them. As most of them have manuscript names, I have thought it incumbent upon me to preserve them where it was possible, though obliged to alter the generic name. The other Fungi are mostly those described by Swartz in his e Flora India? Occidentalism Of several of these I have given figures, which will I trust be acceptable as clearing up difficulties and illustrating some very interesting and singular productions. I trust that one effect of my labours may be to draw attention to a portion of our national herbarium, which, though containing several objects of interest, is perhaps that which has hitherto received the fewest contributions. As regards the species themselves, it is very possible, though I have had access to a large portion of the described species of exotic Fungi, that I may have failed to recognise some already published. If so, it will at any rate be in the power of any competent person to correct the errors I may have made by an inspection of the individual specimens described. I cannot close these observations without making due acknow-ledgement to Dr. Brown and Mr. Bennett for the free and continued access which they kindly gave me to this portion of the herbarium. 1.
